Your outcome, 2H, divided by the total size of the output set. Thus gives you probability 1/12

Multiply the probability of Heads P(x=H | coin) = 1/2 . The probability of 2 P(x=2 | Die) = 1/6. Multiply 1/2(1/6) = 1/12.

snow_tiger [21]

Answer:50 %

Step-by-step explanation:

Given

There are 4 girls and 6 boys in a club

Probability of choosing 1 girl and 2 boys is

$=\dfrac{\text{No of ways of choosing 1 girl and 2 boys }}{\text{No of ways of choosing 3 member out of 10 member}}$

No of ways of choosing 1 girl and 2 boys $=^4C_1\times ^6C_2$

$P=\dfrac{^4C_1\times ^6C_2}{^{10}C_3}$

$P=\dfrac{4\times 15}{10\times 3\times 4}$

$P=\dfrac{15}{30}=\frac{1}{2}$

i.e. $50\%$

You are road tripping down the California coast and you notice you need to fill up your gas tank. In CA, sales tax is 2.25%. You

amid [387]

Answer:

Step-by-step explanation:

So you just have to find 2.25% of 56.

To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:

2.25% of 56

Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:

2.25% × 56

Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.

2.25% = 0.0225

And now you have:

0.0225 × 56

Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.

But once you multiply 0.0225 × 56, you get an answer: 1.26

Hope this was helpful to you, and don't forget to choose the Brainliest answer!

You kayak up a river at a rate of 48 feet every 30 seconds. You kayak 423 feet every 3 minutes on the way back down the river. H

Mariulka [41]

Answer:

You kayak 255 feet farther 5 minutes on the way down the river than in 5 minutes on the way up the river

Step-by-step explanation:

Given:

The rate at which you kayak up a river = 48 feet every 30 seconds.

The rate at which you kayak down a river = 423 feet every 3 minutes

To Find:

How much farther do you kayak in 5 minutes on the way down the river than in 5 minutes on the way up the river = ?

Solution:

Let the speed with which you kayak up the river be x and the speed with which you kayak down the river be y

Then

x = $\frac{48}{0.5}$ [ Converting 30 seconds to 0.5 minutes]

x = 96 feet per minute

Similarly

y = $\frac{423}{3}$

y = 141 feet per minute

Now the distance kayaked up the river in 5 minutes

=> $\text{speed of kayaking up the river} \times time$

=> $96 \times 10$ ( in 5 minutes there are 10 30 minutes)

=>960 feet

Now the distance kayaked down the river in 5 minutes

=> $\text{speed of kayaking down the river} \times time$

=> $141 \times 5$ ( in 5 minutes there are 10 30 minutes)

=>705 feet

Thus

960-705 = 255 feet
